Postdoc position with focus on Qubits in planar Ge

While GaAs structures represent the current state-of-the art in device complexity, Si devices hold the current records in coherence times due to the nuclear-spin free environment in isotopically purified samples. Ge which has been much less studied, has recently emerged as a very promising material platform for hosting spin qubits due to the suppressed hyperfine interaction and strong spin orbit coupling. In only three years a single Loss-DiVincenzo qubit, 2-qubit and most recently even 4-qubit devices have been demonstrated.

In the Nanoelectronics group of Georgios Katsaros we have recently realized a hole spin qubit with dephasing times of 1 μs operating already at fields of 500μT, within the range of magnetic fields currently used for on-chip biasing of superconducting circuits. This was achieved by using the large out of plane g-factors of holes in Ge and by encoding the qubit in the singlettriplet states of a double quantum dot device. In this project we aim to use hole qubits in planar Ge devices and make further steps towards the realization of a hole spin based quantum processor. More information:
